5 CFD Solver - Overview

6 Summary of Features - 1 PDE solver Multi-block capability Parallerised using the SPMD paradigm Flow Physics: Inviscid, RANS, URANS, DES, LES Aeroelastic analysis based on modal representation of structures Moving and deforming grids Modular code with a uniform data structure based on the linked-list concept

7 Summary of Features - 2 Control volume method Parallel - Shared and Distributed memory Multi-block (complex geometry) structured grids Unsteady RANS - Variety of turbulence models inc. LES/DES Implicit time marching Osher's and Roe's schemes for convective fluxes MUSCL scheme for formally 3 rd order accuracy Central differences for viscous fluxes Krylov subspace linear solver with pre-conditioning Moving grids, sliding planes Aeroelastic analysis based on modal representation of structures Hover formulation, rotor trimming, blade actuation Modular code with a uniform data structure based on the linked-list concept Documentation Validation database Range of utilities for processing data, structural models etc. Used by academics and engineers

8 Requirements Minimal requirements ANSI C compiler MPI libraries for parallel computing Grid generation (ICEM CFD at present) Post-processing (Tecplot, Fieldview, Vigie, Paraview) Any Unix flavour will do Optimum (low cost) performance on Beowulf clusters Ported to national computing centres, CSAR, HPCx, IAG

9 Multi-block topologies for rotor cases - ICEMCFD 2-4.5M grid points per blade, blade actuation requires special topologies

10 Add-ons for TECPLOT

11 Probe Analyser - MATLAB

12 Validation Database Distributed with the solver Contains public and restricted cases (sponsorspecific) Public cases are accessible via www Each case is selected to demonstrate and check a particular feature Experimental data are available for all cases Sample results are included
